This patchset supports cluster shutdown and restart. Sheepdog
automatically start only when it is safe. Otherwise you need to run
`shepherd mkfs` or fix manually.
The cases sheepdog doesn't start automatically are:
- There is no local object (before running `shepherd mkfs`)
- All nodes which were in the sheepdog cannot start up
- There is a node which has wrong epoch info.
e.g. mkfs is invoked at another time
- Objects are updated after network had partitioned
When you want to know current cluster status, run the following
$ shepherd info -t cluster
Ctime Epoch Id Nodes
